határfelületéhez

Határfelületéhez is a Hungarian directional phrase meaning "to its boundary surface." It is formed from határfelület, a compound noun meaning boundary surface, plus the possessive suffix -e to indicate "its" and the allative suffix -hez meaning "to/towards." The combination határfelületéhez expresses motion or relation toward the boundary surface of an object or region.

In terms of morphology, határfelület consists of határ (boundary) and felület (surface). The third-person possessive suffix -e attaches to határfelület to form határfelülete (its boundary surface), and the allative suffix -hez attaches to that form to yield határfelületéhez. Hungarian phonology and vowel harmony govern the exact pronunciation and linking of these suffixes, but the core meaning remains “toward its boundary surface.”

Usage-wise, határfelületéhez appears in technical or geometric prose when describing proximity or direction relative to a boundary surface. For example: A görbe közelít a test határfelületéhez. (The curve approaches the boundary surface of the body.) Such constructions help specify spatial relations in three-dimensional contexts, such as geometry, physics, or computer graphics, where precise reference to a boundary surface is required.
